DEVICE FOR CONVE TING MbTlOhl.

SPECIFICATION To all whom it may mean.-

Be it known that I, EDWARD ALMERON MOON, a citizen of the United States, residing I reciprocating motion can be turned into ro-. tary motion, and hasfor its objectjto provide a simple and convenient device whereby any L I at Cleveland-in the county of Quyahoga and State of Ohio, have invented a new and useful.

Device for Converting Motion, of

following is a specification. I I I My invention relates to a device whereby which I the kind of reciprocating motion can be converted into a rotary motion, and particularly to proi view of the internally-spiraled portion of the clutch. Figs.. 5, 6, 7, and 8 are details of a V modification of the clutch, whereby the same may be reversed and locked in position. Fig. 9 is a detail of the spiral rod. Fig. 10 is a perspective of a platform rockingchair to which my device is attached for the purpose of operating a sewing-machine. Fig. 11 is a cross section of a portion of the same, showingthe 1 operative mechanism.

The end of the- I I roughened surfaces M M and the groove M, in which lies the ring N, provided with the pins 0 0. These pins project through the inclined grooves L L in the end of the cylindrical part L. The case of the clutch is composed of the two portions P and P, properlysecured together and composed of sections; On the portion 1? there is the ledge P beneath which lies the edge of the collar P, which has the handle 19* thereon. This collar is provided with internal grooves, P parallel with the length of the cylindrical portion L, and into which the endsof the pins 0 0 project. I have shown in the modification one end of the sliding clutch. The other end, of course, is the same, though reversed, as is clearly understood from an examination of Fig. 3.

. On the outer surface of the portion 1? is secured by a bolt the spring It, having the pin R on its inner end and passing through the aperture It in the raisedportion 1-? on the part P and engaging a series of notches on the portion P thus locking the same in any position it'may be desired.

The use and operation of my invention are as follows: I have described, first, a device for converting reciprocating motion into rotary motion, as illustrated in Figs. 1, 2, 3, and 4, which may be employed easily for any purpose or in any machine where it is desired to make this change. The parts having been set in position, as shown in Fig. 1 or Fig. 2, with the gear-wheel or the pulley and belt in proper connection with the parts to which the power is to be applied, the rod T is connected with thepiston of a steam-cylinder or with any other power -supplying device from which power is to be derived. The ends U U are pivoted to one end, J, of the sliding clutch, or they may be pivoted to any part of the cylindrical portion G, or to the opposite end of the clutch to the part '11. It, now, the power he applied so that the rod T is reciprocated, the sliding clutch will be reciprocated along the rod B. The rod B will be held on its standards A, so as not to move longitudinally, but be free to rotate in the boxings onthestandards. The internal spirals, H and J, in the ends of the sliding clutch will engage, respectively, the spirals (l and G on the rod B. Now, while the sliding clutch is moving toward the left or toward the pulley or cogwheel on the end of the rod B, it will be apparent that the friction of the rod B within the spirals on the ends of the clutches will cause the flange H to press against the packing or roughened surface H, where it is held from rotation, and the further motion of the clutch in the same direction will cause the spirals C on the rod B to travel in the spirals H of the end of the clutch, and thus the rod B will rotate on its standards A A. This rotation will be in the direction of the arrow. When the clutch has reached the end of its stroke toward the left, the reverse motion of ends constructed as shown in Fig. 3,on the rod B, having its portions oppositely sp'iraled, as shown, a constant rotary motion will be 1mparted to the rod B, so that the reciprocating motion imparted to the sliding clutch will be transmitted in the form of a rotary motion by means ofthe gear-wheel or the belt and pulley to the machinery to which it may be desired to be applied.

I have illustrated in Figs. 10 and 11 how this device can be employed in operating sewingmachines. There are many instances where it is desired that a sewing-machine should be operated by means other than those commonly employed, and I have adapted my device for use upon a rocking-chair, so that the motion of the chair can be employed to operate the head of the machine, the head being clamped to the arm of the chair and the band passing from the fly-wheel in the usual manner. This fly-wheel is secured to one end of a doublespiraled rod like the rod shown in Fig. 1, which is journaled in the rocking portion-of the chair. On this are mounted the sliding clutches, as shown in Figs. 1 and 2, which are linked to the rock-shaft, which rock-shaft is secured in the rocking portion of the chair at right angles, or nearly so, to the frame of the chair, and at its opposite end is attached by links to the permanent or platform portion of the chair, so that by rocking the chair the rockshaft is set in motion. The arm which depends from it is rocked back and forth. This motion causes the sliding clutch to reciprocate on the rod B, thus giving it a continuous rotary motion, which motion, by means of the belt, is communicated to the sewing-machine and the same is set in motion, as indicated in Figs. 10 and 11. Now it is possible that in some cases and in some devices where my invention may be applied it may be desirable to reverse the motion of the rod. It might be desirable to have the belt travel in a direction opposite to that indicated by the position of the arrow. This I accomplish by means of the mechanism illustrated in Figs. 5, 6, 7, and 8. The internal spiraled piece in the end of the clutch is provided with a flange, upon each face of which is placed the packing material or roughened surface, though the same might be placed on the opposite walls of the chamber in which such spiral piece moves. This spiral piece is provided at its inner endwith a projecting portion, which is inserted within the end of the cylindrical connecting-piece. It has also the groove in which lies the collar N, with the projecting pins 0 O.

position after the end M is inserted within the end of the cylindrical portion L, the pins projecting through the slots, thus locking the spi raled piece to the end of the connecting cylindrical piece. The shell in which the flange of the spiral piece moves is composedjof two or more portions secured together and in suitable'sections, and on the outside of the sections of the shell portion P is aledge which holds the collar P in position. This collar plays upon the side of the shell, encircles the end of the piece L, and is provided with the handle P, by which it can be turned on the cylindrical portion L. It is also'provided'with the'slots P which areparallel to the length of the cylindrical portion L and receive the pins 0 O. The ring Nhasaslight playin its groove. Now, by moving the handle P and rotating the collar P it will be clear that the ring N will be rotated in its groove, and as the pins 0 travel in the diagonal slots L" L theposition of the portion M will be changed-at will. By moving itin one'direction the packing-surface is brought in close proximity with the left-hand inner wall of the shell. By moving it in the other the packing-surface M is brought near to the other inner wall of the shell. When the clutch is moving toward the left,the packing-surface M will be free from the inner wall of the shell, so'that it cannot touch the same,

and whenthe clutch is moving towardthe right the spiraled pieceqM will be locked.

against the inner wall of the shell and the rod will rotate. When the clutch is moving in the opposite direction, the action of the spiral Thus by turning the handle P the position of so that it will engage either wall at will, and.

the flange on the spiral piece M may be fixed at any convenient point within the shell. The

"parts may be so set that the spiraled piece M will engage neither of the walls, and thus they will be thrown out of operation altogether,or"

thus, by setting the-structure as shown, the rotation of the rod- B may be changed at will. When the handle P has been moved far enough to throw the spiral'piece M into the position desired, it is important that it should be locked in that position, so as not to slip,

and to effect this purpose I have provided a spring, R, carrying the pin. R which engages thenotches on thegedge of the collar-P thus locking the same in any position where it may happen tobe.

The operation. of the modification shown in o of the clutches depends uponthe side of their f Figs-5, 6, 7, and 8 is as follows: The action caseson which they lockas, for instance, if the clutches lock on the side of the case toward the connecting-piece, as shown in Fig.

3, then the spiral shaft willmove in a certain direction. Now, if those clutches were soar-j rangedas to look upon the oppositesides, it must be apparent that the spiral shaftw'ould rotate'in the oppositedirection, for, in the f; 7

vfirst case, when the shaft is moved toward the left,theright-hand clutch is locked and causes it to rotate. When it is moving towardthe I right-,the left-hand clutch is locked and causes it to rotate in the .same direction. If, now, .when'moving'toward the left, the left-hand clutch were locked and the righthand end loose, it is apparent that the spiraled shaft will rotaterin theopposite direction. Now, i 7

the devices shown in Figs. 5, 6, 7, and, 8 are i simply designed to present means whereby.

the position of the clutches in their cases may. I be shifted so that they may be locked upon either side of the'clutch, as desired.
